The Blue Marble is turning into a glowing globe – and in many places that’s becoming a problem for human health.

Atlantic salmon from Norway carry a dangerous disease that puts native Canadian fish at risk — and maybe those in the United States, too.

New research shows that 2,000-year-old baobab trees are suddenly dying. New trees won’t have a chance, either.

Chemicals collect in microplastics, which then get eaten by fish, birds and seals — and by humans.

As extreme weather conditions arrive, vulnerable people in migrating populations could find themselves at risk from sexual exploitation or forced labor.
